WGPU Mojo

This repo shows proof of concept bindings to wgpu-native. These bindings are not in a state such that they can be used for anything production ready, but one can at least reach a hello-triangle stage.

There is an example that can be run with:

magic run exec

respctively.

Note: the C binding generator in gen_c.py is currently stale, so running it will break things.

Limitations

• I've only written code to get the surface for MacOS.
• There are several structs like WGPURequestAdapterOptions that don't seem to work when used in an FFI call.
• In an FFI-callback, accessing the status struct seems to cause issues for some reason (but works if replaced with an UInt32).
• Due to the awkward stage the Mojo standard library is currently in with respect to collections (and the CollectionElement trait), some types need to be wrapped in Arc so they can be used in collections.
• Lifetime inference doesn't seem to be working well for structs like RequestPipelineDescriptor.
